James Tynion IV Confirms That No, Punchline is Not Master Bruce

Matthew Warner was a character created by Tom King and Travis Moore, a young boy from a wealthy Gotham family who became obsessed with Bruce Wayne and ordered his butler to murder his parents to be like him. Afterwards, he began calling himself Master Bruce, and scratched the words "Thomas" and "Martha" into his cheeks. He was later incarcerated in Arkham Asylum.

I've seen this floating around, with zero idea where it started. Punchline has no connection to Batman #38 or the characters introduced there, and did not appear in any comic book before Batman #89! https://t.co/4IMVRhmwdN

Indeed… Matthew is a Tom King character after all. And very little of anything Tom King-related will appear in Tynion's Batman… pretty much the point. And also, would DC Comics make a seriously mentally disturbed individual their most prominent trans character right now? On purpose? In 2020?
